Just back from a weeks break up in Scotland, drove up and down from Bristol, about 550 miles each way

Have to say, MPG is absolutely dire for a diesal - 37mpg on the way up, 35 on the way back down again

I wasn't pushing the car either, driving nice and steady, mostly motorway and dual carriageways. 70-80mph, 6th gear where possible.

Yes, had quite a full car, but still would expect far better results. around 450 miles to a tank is :tsktsk: IMHO, used to get 600+ on a 60 litre tank on my old 7 seater MPV and that was without even trying to drive carefully.......

And I am told by dealer car had all the latest ECU work on it to improve MPG - not sure I now believe them........

I know it's been covered many times, just wanted to let my frustrations out!

Seems to me the 220d has no advantage fuel wise over the petrol engine. My 57 plate 250SEL auto has now managed 37.8mpg over 4000 miles. Ok. a lot of motorway friving at a steady 80 but impressive in my view

I totally agree re the diesal over petrol argument (or lack of) - mine was not too bad when new, now done 6,000 miles from new and it appears to be getting worse.

Is that possible??????

Been many times where you are (i.e. frustrated)....how many miles you done altogether since new now?

I filled up last week - the MPG to empty showed 12 miles, had covered 526 miles since last fill, and this time put in some Total Excellium for the 4th time in a row. No difference in consumption or power - feels the same as Reg derv...car averages low to mid 40's with a gentle driving style (28-33 in town only driving or 45-48 motorway only). It just cost me 3p p'leeta more for no benefit...feel like a mug

The best pace/MPG on mine is:

57-60 in 5th - 50-53mpg

70-74 in 6th - 45-48mpg

- using cruise where ever possible...

BTW - I'm on 15k almost

6000 miles on the clock now on mine

was watching the current mpg as best I could on the drive back, in cruise all the time, was frightening to see it only a fraction above 30 at 80mph in 6th gear

Your engine is still quite tight at 6000 miles, it should start to loosen up at about 10,00 miles, when you should start to see your mpg improve, and the engine feel more responsive.

Rubbish, no it will not!!

Currently on 52000 & returning an average of 34.6mpg. Mostly motorway mileage

Matus advised changing up @ 2000rpm about 12 months ago but the latest mod (10 days ago) means doing this makes the idle/lumpy.

Yet again really fed up :tsktsk:

That's harsh (the 'rubbish' comment). I've done just over 13k miles, the ECU mod and 5th injector have been done, and I'm getting an average of 40.6 mpg. The car did appear to improve at 10k miles as had been predicted. Perhaps your 5th injector is clogged? When mine was I was only getting 33 mpg at best.

Just my tuppence worth :)

I find it very interesting that just about everyone here seems to be disappointed on the fuel economy of the 220d. I have the Sport version and have never had a total tank average worse than 43 MPG. On pure motorway the tank AVG is around 48-49 MPG. It's not the most economic diesel in the world, but it's just fine in that aspect as well. I have done about 8500 miles on mine. I haven't noticed any dramatic improvement on the mileage, but the responsiveness has got a lot better since new. Performance/economy ratio is spot on, IMHO.

Think I'll get it checked over at it's first service, if not sooner (hand brake very slack, could do with tightening before 10k service)

There does appear to be a huge range of figures being quoted and I cannot believe it should be quite as dire as mine is returning, even when being driven quite conservatively

thanks for the comments as ever!

Now done 2500 miles in my 220d sport and I am utterly dissapointed with MPG. My tank average is 27mpg. Yes it's new, yes it needs time to bed. But come on, this is the forth brand new diesel I have had and none of them were this poor to begin with. Yes I agree it will improve over time but not to a level that is acceptable for a diesel. May well have gone for the petrol with an auto! Yes I hate the manual gearbox, how on earth did quality control let that through I will never understand.

My experience mirrors exactly everyone else's: the 2.2D engine simply does not suit the IS. I have now done 15,000 and the MPG hovers around 37-38, with mostly m-way driving or gentle B-road. This is quite frankly appalling, and I have regretted not buying the petrol auto almost every day.

If there are any potential punters out there: BUY THE PETROL AUTO. If I was offered a decent trade-in I would switch tomorrow. The fuel consumption is identical on the diesel manual and petrol auto models, and I am a private buyer so no tax benefit to the diesel.

Sorry to be so negative, but Toyota is not a diesel specialist - petrols and petrol/hybrids yes, diesels no.

This post really shows the value of this forum. When I started looking for a new car back in the summer I was attracted to the IS. Coming from an auto Audi diesel my first choice was to try the diesel IS. What a terrible disapointment (see my earlier post "diesels are sluggish").

I also tried the 250 auto, and was smitten. After much advice and research on this forum I bought a 250SE auto although I still was a bit unsure if I had done the right thing going back to petrol.

After 8 weeks ownership my car has averaged 34.9 mpg (I zeroed the average mpg on the day I got it).

On a 400 mile round trip last weekend tackling the M25 and M1 widening roadworks and doing 80mph + where possible my tank average was 39.1mpg.I am sure if I had travelled slower and not got held up so much, it would have been well past 40.

The car has definately grown on me, I love the smoothness and ease driving it.The ML sound is great, and I look forward to driving it every day.

Thankyou everyone on the forum who adviced against the diesel.I am so glad I took that advice.

Al.

The petrol automatic is obviously a more comfortable ride, but seriously: the fuel consumption is NOT identical. I admit I haven't driven the petrol version apart from a couple of quick test drives, but I have a 1.6 petrol Corolla with manual tranny and I can barely hit the same figures that I do with the 220d Sport. Now, the 250 auto is a lot heavier car than the Corolla, it has a lot more power and it has automatic transmission. There is NO WAY it would give me the same mileage that I get with the Corolla and 220d.

One thing is for sure: you have to really concentrate to get proper mileage from 220d. The petrol auto will surely give a more consistent mileage regardless of your driving style.

Please don't take this the wrong way FinLex, but why should I have to "really concentrate" to get proper mileage from a car? I want to drive like to always have done - quickly, but smoothly, and without worrying "ooh, did I rev it too much? will it affect my mpg?". THat's just ridiculous.

It's really simple: if you wan't to get proper mileage out of ANY car, you have to drive accordingly (edit: at least with a manual, autos are more consistent). If you don't care enough to make the effort, you shouldn't be complaining. The 220d is in this sense a bit more demanding than many other diesel cars, but it will give decent mileage if you go through the trouble to alter your driving style.

One more thing. You can accelerate as fast as the car will go and still get proper mileage. It's not accelerating that kills your fuel economy, it's braking! My driving style is: quick acceleration, quickly to the right gear and then steadily onwards avoiding unnecessary braking and stops.

I accept all of that - but the problem is that my car before my 220d was a M-B 270CLK, which I could drive as aggressively as I wanted using its auto box, and consistently get 45MPG in mixed driving. I do accept that this car didn't have the latest pollution reduction technology, but still...

I feel I have to defend the 220D here. I have a '56 Plate, which when new struggled to return over 36mpg even on motorway journeys. As per all the other comments 6th was useless unless it was doing 80mph+

The fuel economy has slowly but surely improved as the mileage has increased - Usually returning around 40mpg for a motorway trip, cruising at 80mph once it passed about 15K

The car has now just passed 30K, and I have noticed a huge difference in the way it drives and performs in relation to mpg. Cruising at 80mph it's now returning 45mpg per tank, and for the last few weeks I have tried cruising at 70-75mpl in 6th which now feels perfectly acceptable, and the car is returning 50mpg per tank. Couldn't be happier!

I think it's a case of the more miles the better with this one.

oh, and for reference this is on standard derv from Tesco.

All I seem to do is come on here and moan! I think my car must just be a Friday car!! So far, Lexus Leicester has had my car in for 10+ days. Working on 5th injector, then all jets replaced which increased the mpg from 32mpg to 35mpg (on motorway journey 40+).

Then 6 weeks ago the car started to seem sluggish and lumpy. 48hrs later the car went into limp home mode, which took 3 days to fix but the car has remained sluggish since and the mpg has dropped back to 32!! As previously mentioned the car went in for its 50k service and a new mod was applied. Yesterday I drove to Folkestone and back (355 miles) with the following problems. 1st gear is dangerously slow until 2500rpm when the turbo comes in and in the rest of the gears @ under 2000rpm the car is hesitating! Car is booked in again next Friday – watch this space!! The really worrying thing is that I am very quickly approaching 60k and the end of the warranty!! :crybaby:

I like Jamboo, Matus and others have contributed to this topic on numerous occassions.

I have done 26,000 klm and currently have an overall return of 6.0 litres to 100/klm that is 47.1 average since January 27th 2007.

Due to its gearing this car is different....what you did before in other cars does not count.

Its like learning to drive again...to get the best from this car you must drive it optimally.

My current tank is 6.3litre per 100klm = 44.8mpg for me this is bad!!! Usually 5.8 to 6.1 = 48.7 to 46.3 mpg.

I do believe, but he can speak for himself...that Jamboo changed his habits of a life time and experimented how he might get the best from the car and I believe he is now satisfied that there's something to be learnt and his only gripes (justified) appear to relate to the creaks & groans of the car chasis and cockpit etc.

The 220D for me is the best car I've ever owned..I have owned Mercedes E200 x 2 before and they are not any where in comparison.

So whats to be done??? TRY A FEW DIFFERENT driving styles...just because it looks like the Starship Enterprise doesn't mean warp factor 6 Mr. Zulu all the time.

Things change...Lexus are spearheading a new breed of cars, technology and legislation limit the possibilities...ALL manufacturers are chasing after Lexus in this respect...when they catch up we can then start to compare like with like...and you'll see that we've moved on a Tad...give the car a break...calm down...relieve the stress levels...sit back and enjoy.

I dont proclaim to know it all, I dont want to be condescending in any way in any of my comments. You're all great guys'n'gals with a new breed of car that's the envy of many because its different. If that means you have to change ...accept it...change...see what happens.

Thank you Vrmm Vrmm, Im coming from an '04' Mk 3 Mondeo TDCI 128bhp to a 220d next week. Ive worked up my paranoia to an extent that I thought Id made the wrong decision.

I have done 90k miles in the Mondeo in 3.5 years and I have to say I have found it comfortable, quick (ish) and reliable (apart from a split Turbo hose which was replaced under warranty it has never been in the Stealership). I was sorely tempted with the new Mondeo but with a wait of 16 weeks and the thought of having my 4th Mondeo on the trot i decided against it.

Your comments have given me hope that I havent made the wrong choice and I think that apart from the odd horror car some of you have generally the car is extremely good and owners expect perfection, I dont I just want to be made to feel im in a better standard of car than my old Mondeo. I dont even mind the odd breakdown as long as I am treated well at the dealership.

I only hope in 3 years I can be saying the same thing on here and not be on the Audi/BMW forum.

Duncan
